Dear libmesh developers:
 
Roy told me that METIS can work well in libmesh and ParMETIS can't work well. I want to know whether the problem has been solved. If not, where is the key problem? In addition, I want to confirm that libmesh will call METIS for mesh partitioning after libmesh reads the mesh data. thanks a lot. 
 
best regards,
Yujie
